Kornev O. Method for Complex Aerodynamic Design of Airframe&Propulsion System Using a Combination of Numerical and Model Experiments

Оbject – multi-mode aircraft of integrated aerodynamic embodiment; goal – to create a method of aerodynamic design of aircraft integrated configurations, the competitiveness of which is achieved, from a technical point of view – increasing aerodynamic excellence, flight and other characteristics by gas-dynamic integration of air-jet propulsion system in the carrying system, with methodical – reducing the required design resources through rational use of economic design tools methods of numerical and model experiments; methods – methods of physical and mathematical modeling; results – the principle of the working process with continuous supply of air flow to the deep inlet device of the air-jet engine, the method of aerodynamic design of integrated aircraft, the layout of the airframe-engine system with the upper inlet device and using external vortex generators; novelty – further developed the method of aerodynamic design of aircraft of integrated layouts, which allows to take into account the peculiarities of the mutual influence of the engine and airframe, on the basis of the further developed method of aerodynamic design the structure, parameters of currents and integral aerodynamic characteristics of system airframe - the engine taking into account interference of streams are specified, for the first time an improved integrated layout of the glider-engine system was proposed, in which the air-jet engine of the tunnel layout is connected to the direct creation of aerodynamic forces by means of a vortex-free deep inlet device with external vortex generators and an ejector nozzle; degree of implementation - implemented in “SME” “Ukrradioprom”, Research Institute of Physical Modeling of Aircraft Flight Modes of the National Aerospace University KhAI, SE “DB Pivdenne named after M.K.Yanhel”; field of application – aviation.
